老師的一句話

 中大盧煜明教授獲拉斯克獎,他分享經歷時,說在英國習醫時,「教授話呢個技術(無創產檢)可以改變世界喎,我都想學吓點樣改變世界。」

Genious Hour Project Ideas

 先前說過今年教undergrad的materials design and adaptation 一科,發覺今年這一組不少學生都很technology-savvy, 對製作digital learning resources 很有興趣,於是我突然生起genious hour project 的念頭,鼓勵學生超越課程的要求,去explore和create更多有創意的learning object。我聲明會有額外的credit, 但不會很多,希望他們基於興趣和自主學習精神,作額外的探索。


這是我第一次作這樣的嘗試,我也不肯定學生會有回應,他們都是DSE的勝利者,很習慣求學就是求分數。


兩個星期下來,果然有不少的學生有回應,這真有點喜出望外,當然上課時我會表揚一下,希望更多同學享受為學習而學習,甚至有一天他們回想undergraduate 的final year, 曾經狂熱地製作learning object, 不是追求額外的分數,而是因為享受這creativity 的過程。

Genius Hour Projects

 今年教的其中一科undergraduate course是materials design and adaptation, 在今天這digital age, 教材製作當然離不開ICT, 而今年這一组特別Technology-savvy, 组員有Microsoft Certified Educator和Google Certified Educator, 每一課都很快便完成我指定要製作的learning resource。

那天我突然有一個想法,既然他們有這個能力和潛質,我為何不鼓勵他們超越課程的要求!於是我作了新嘗試,稱作Genius Hour Project,就是除了完成指定的工作外,他們如果有興趣,可以額外發揮他們的creativity, 用自己的創意製作更多的learning resources 。為了刺激思考,我给予他們一些Genius hour project idea,下面是製作listening resources 一課的genious hour ideas。

這個意念是否work, 暫時我不知道,一個可能是額外分數不多,於是學生反應不積極。另一個可能是這激發學生的intrinsic motivation, 於是他們不計較分數,享受過程和看到額外心血結果而自豪。

無論結果如何,這都是一個有趣的實驗。

The Dictation Game function in Educaplay

 Educaplay has an activity format, called Dictation Game, which can be useful to English teachers in preparing their students for Dictations. You (1) input the dictation text, (2) record the text word by word or sentence by sentence, (3) 'publish' it, and (4) give students the share link. 

At home, students then listen to each word/sentence, and type it out. They can replay a word/sentence as many times as they like. When they have finished typing out the whole text, they click 'Check'. The screen will then show them (a) the original text, (b) their typed text, and (c) their mistakes highlighted. 

Below is a short P2 example that I have created. Give it a try and see if this function is useful to you in preparing your students for Dictations.

Froggy Jump in Educaplay

 像Bookwidgets一樣,Educaplay 也是我早期用以製作interactive task的其中一個app. 但出現了其他更versatile 的app後(e.g., Wordall),便被我冷落了。最近重訪Educaplay, 發現它有一個新的game mode稱Froggy Jump, 基本上仍是MC Quiz, 但它的版面 很有趣,答問題時令青蛙跳來跳去,初小學生應該會覺得很好玩。

還有,學生答完一次後,可以無數次retry, 每次retry, 题目的次序會改變,無題三個可能答案的位置都會掉換,這樣學生不能靠死記正確答案的位置,而且retry多次也不覺得悶。

下面是我用Froggie Jump製作了一個present tense verb form的game。

今天的Educaplay 還有一個Activity type對小學英語老師會很有用,就是Dictation Games, 可用來幫助学生温習默書。

Thinglink vs Genial.ly

 GeGenial.ly is still worth subscribing to (HKD30 per month) as it has a larger variety of artifact types, and for presentations you can upload your PPT as a starting point.

 With Thinglink, to use a template you have to go to the built-in Canva connection, but sometimes you have to pay to use a Canva template. But Thinglink has (a) 360 artifacts which Genial.ly doesn't have, and (b) seats for students. These are two unique features that Genial.ly doesn't have.

Ice vs water

 喜歡喝台灣的黑糖珍珠奶茶,但去不到台灣,惟有在香港小店買一杯來喝喝。


但是跟著途中一直找不到適合除下口罩的角落來喝這杯看上去也頗像樣的黑糖珍珠奶茶。走著走著,突然想:內裏的冰塊會隨著温度上升要溶化,杯內愈來愈多水,會否迫破膠杯的封口?


過一會想,冰溶化變水後,水的體積會否比先前的冰塊細小,以至愈多冰塊溶化,杯內液體的體積反而愈小。這一刻,發覺自己竟然不知道答案。


隨著想起中學的物理科老師兼中五班主任馬紹良先生,覺得有點愧對他,尤其是他教物理着實教得好。幸好幾年前碰見他,他還記得我的名字。


如果你在IT和e-learning 界的日子夠長,你也可能記得他的名字呢!不錯,馬绍良老師後來進入教署,做到資訊系統科首席教育主任,負責推動全港學校資訊科技教育,說他是香港資科技教育始祖,一點兒也不為過。


雖然我已經把老師教的物理知識全然忘掉,雖然我的專業不是資訊科技本身,但我愛上了computer assisted language learning, 也算是對馬绍良老師一點報答吧。
